Title: Plinth device for tile stoves
Inventor: LAMPKA BRUNO
IPC: F24B1/02
Filed: 1981-01-26
Abstract: The plinth of a tile stove has at least one prefabricated wall element which consists of a supporting frame and of a cladding plate. The latter can have an arcuate orifice. The supporting frame consists of profiled rails accessible from inside the plinth and serves, firstly, for absorbing the weight of the tile jacket and for supporting the stove batch and the reheating devices, in that mutually opposite supporting frames are connected by means of profiled supporting rails. The supporting frames of mutually opposite and/or adjacent wall elements can be connected to one another to form a plinth frame. The new plinth element can be prefabricated fairly cheaply and increases safety against subsequent damage, because the heavy supporting loads of special profiled supporting frames are diverted into the ground and the cladding walls are therefore largely relieved. <IMAGE>

Title: Drive with a vertical shaft for surface aeration of liquids, especially water
Inventor: FOGARASI FERENC DIPL ING
IPC: C02F1/74
Filed: 1981-06-11
Abstract: Drives with a vertical shaft for surface aeration of liquids, especially water are subject to considerable loads, owing to the aeration rotor shaft projecting and the interferences of the liquid pressure differences caused in the liquid as a result of the aeration. In order to absorb these loads, the inertia and the external dimensions of the components are increased according to the prior art. At the same time, according to a known solution, the aeration rotor shaft, which at the same time constitutes the driven shaft of the transmission, is subdivided into a rotorshaft and a driveshaft which are linked by a clutch with internal and external gearing. The teeth of the clutch are subject to rapid wear, since as a result of the forces, previously mentioned, which act on the shaft the outward bend of the rotorshaft is very large. In order to reduce the tooth pressures on a clutch, geared in this manner, of a relevant drive and, at the same time, to be able to dimension the shaft of the aeration rotor in accordance with the conventional transmissions, as far as possible, there is provided at the driven shaft a clutch half (4) with external gearing which is shaped like a barrel, and the axial spacing between the toothed face and the bearing (5) situated nearer the clutch (3, 4) is dimensioned in such a way that said spacing does not exceed one half of the external diameter of the clutch (3, 4). <IMAGE>

Patent DE-3127572-A1 (DE)
Title: Rotating shear for rolled bars
Inventor: ZWICK GERHARD
IPC: B23D25/12
Filed: 1981-07-13
Abstract: The object is, ahead of the cooling bed in light and medium section mill trains, to cut both large round and square section bars moving at a relatively low rolling speed and U, L and T sections moving at low to high rolling speeds with a quality of cut equal to that provided by a parallel blade cut and also to cut small round, square section and flat bars, which do not require a parallel blade cut, at even higher rolling speeds, and to do this with one blade per strand. This is achieved by virtue of the fact that, with a shear which starts from the stationary condition and has crankshafts mounted in eccentric drums and a swinging linkage to keep the blades in the blade carriers parallel during cutting, the cranks of the crankshafts drivable in the eccentric drums via chain drive elements are connected to cranks of equal length, rotating in the same direction and at the same speed and bearing connecting rods, of crankshafts supported in the shear housing and engageable by means of clutches, the connection being effected by means of divisible blade carriers which are supported on the connecting rods and are seated rotatably with their blade-carrying blade heads on the first-mentioned cranks. <IMAGE>

Title: Ventilation grille for car windows
Inventor: JUNGE ERNO
IPC: B60H1/26
Filed: 1981-08-12
Abstract: In the hot season the car windows are wound down somewhat for temperature moderation and ventilation. Of course there is then a draught in the car. If the car is parked, this often only being possible in hot sun, with the windows closed a sweltering heat is produced in the car. Leaving the windows slightly open encourages car thieves. The invention solves this problem by using a ventilation grille which can be inserted between the upper edge of the somewhat opened window and the upper door frame and with the window correspondingly wound up is secured in the door frame. The ventilation grille is provided with oblique lamellae which deflect the wind, making draught-free ventilation in the interior of the car possible even when driving at high speed.
